    4.1.1 Detection zone and approach The protective field of the SLG 422/ 425I-P is 500 mm. The output and input of the beam is shown in the dimensioned drawing. Install additional protective structures to make sure that the detection zone must be passed in order to reach dangerous machine parts.

  • Page 8: Minimum Distance To Reflective Surfaces

    400, 900 ! Attention Always keep the safety distance between the SLG 422/ 425I-P and the danger spot. Any person that can reach the danger spot before the dangerous movement has stopped might get seriously injured. 4.1.4 Minimum distance to reflective surfaces ! Attention When installing SLG 422/ 425I-P the effects of reflection from specular surfaces must be considered.
  • Page 9 D [m] The effective aperture angle for the SLG 422/ 425I-P is +/- 4,0° (when L > 3,0 m) as provided by the IEC 61496-2. Install the SLG 422/ 425I-P away from reflective surfaces at an effective aperture angle of +/- 5,0° to take misalignment during installation into account.

  • Page 10: Operating Mode Muting

    Safety light grid SLG 422/ 425I-P 5 Operating mode Muting The Muting function is an integrated operating mode of the safety light grid SLG 425I-P. 5.1 Intended use The Muting function is only applicable for automatic material transport to secure access points of a danger zone.

  • Page 11: External Components

    Safety light grid SLG 422/ 425I-P 5.5 External components 5.5.1 Muting sensors MS The muting sensor MS can be a mechanic, capacative, inductive or opto-electronic sensor. There is no specific requirement concerning error protection. The arrangement must be secured against manipulation.

  • Page 12: Muting Lamp

    The Muting mode must be indicated by an external lamp. Connect this lamp to the sensor connector plate (ML) using a 3 pin cable connector. The muting lamp is not monitored, i.e. the control unit of the SLG 422/425I-P does neither check the electric connection nor the illuminant.

    Safety light grid SLG 422/ 425I-P 5.8 Setting for muting operation When you have properly connected the muting application and the NSR-0801, select the following parameter settings according to your intended application in the menu option Muting Function of your PC software.

  • Page 14: Restart Interlock

    A new muting cycle can only be started when none of the muting sensors are dimmed. 5.9.6 Override Use this function to bridge the outputs of the SLG 422/425I-P in case of an interrupt (voltage interrupt, material jam). The function has a time restriction and is expressly intended for the removal of the material jam (muting sensor or protective field dimmed).
